Flexing isn't just for the gym anymore people. There are plenty of every day activities that can provide the perfect excuse for you to exhibit your well-maintained pythons. Show off those biceps while brushing your teeth. If you are at a funeral and you have to do one of those solemn "hands clasped in front of you" poses, go ahead and tense up those triceps. Almost any time a camera comes out, you can cross your arms, pop those pecs, and show off the fruits of your bench press labors. Get creative, but remember, if the world notices that you are flexing, your vanity will be revealed, so be subtle when you're making those muscles.
Find excuses to flex your muscles.
